For a binomial times a binomial, use FOIL. FOIL stands for First, Outside, Inside, Last.
\left(x\,+\,2\right))
First:  (the first terms of each)
Outside:  (the first term of the first binomial and the last term of the second binomial)
Inside:  (the last term of the first binomial and the first term of the second binomial)
Last:  (the last terms of each)
Add the terms:
Collect like terms:
There is nothing particularly sacred about the order in which the operations are performed. It is just that Outside, Last, Inside, First = OLIF doesn't spell anything that a student would be likely to remember, and neither does FLIO, LFOI, etc.
